I dunno if its a translator error or an author error but they keep using Sister-in-Law points. Am I missing something or is she not his STEP-sister?

She gives herself sister-in-law points because she didn't accept the rumours about Kazemiya who is her brother's gf (she wasn't at that time but you know what I mean)
